Another object of particular case in hand.

This invention is particularly adapted for use The pipe 8 not only serves to support the upper 35 in applying a liquid to a thread, and is especially end of the screen I, but also provides a means useful for the application of conditioning oil to for conducting the thread treating fluid to the artificial silk filaments such as are produced by screen. The pipe 8, as best shown in Fig. 2, is the dry spinning method. provided with a valve H which controls the flow It is desirable to have such delicate threads or of fluid into the pipe 8 through the pipe i2 which 40 filaments contact with as few parts of the maleads to a supply tank IS. The valve H can be chine as possible, and where the filaments pass readily adjusted to deliver the desired quantity around guides, it is desirable tohave the contact of fluid necessary for the operation of the mawith the guides short. chine.

I have found that a smooth, satisfactory guide The pipe 8 is provided with one or more per- 45 and fluid applicator for thread can be made by forations Hi through which the fluid I5 is adutilizing a wire-mesh screen in which the indimitted to the wire screen I. Since the wire vidual wires which make up the screen are screen 1 is composed of wires each substantially smoothly rounded as such a screen forms an enround in cross section and woven back and forth,

tirely satisfactory contacting surface for the delithere are a plurality of interstices between these 50 cate filaments. wires which will receive the fluid l5. Moreover,

The mesh of such a screen naturally varies with the fluid will flow through these interstices by the desired results. If considerable material is to gravity and capillary attraction and will thus be applied, a coarser screen may be used, or if conduct the fluid down to the point where it less fluid is to be applied to the thread, the screen may be absorbed by the filaments. 55

Thus, in Fig. 3 the fluid l5 passes through the opening l4 and may flow down the wire mesh screen 1 so that it will pass about the wire supporting rod 9. Consequently, the filaments 3 which contact with a small area of the wire 1 as it passes about the rod 9 absorb the fluid from the meshes of the wire screen. By adjusting the valve H, the flow of fluid can be readily controlled. i

If desired, the wire screen I may be made of suflicient width to take care of a series of different spinning heads as the meshes of the wire by capillary attraction deliver a very even flow of fluid to the contact point.

I have found that it is preferable to arrange the individual Wires H of the screen so that the wires passing in both directions will be at an angle to the filaments 3 and preferably so that they will both be at an equal angle. The reason for this is that the filaments will then have equal contacts with the various wires making up the screen and the fluid will be applied and gently r ed into the filaments as they pass about the r0 9.

I also believe that such an arrangement of the wires causes the fluid to flow more evenly overall parts of the screen, although satisfactory resultscan be obtained with the wires running parallel to the filaments.

{is the filaments are drawn around the wire screen 1 as it passes around the rod 9, a certain amount of the fluid is removed, but as fast as a small area of the wire screen becomes undersaturated with fluid, the capillary attraction of the screen for the fluid quickly fills in the meshes of the screen so that a very even supply of fluid is deliv r d- I WhileI have described my fluid applying mechanism as being applied to the spinning cabinet of a dry, spinning machine, it is very obvious that such a device can be placed anywhere and may be used in connection with any machine which requires thread guides. It is possible, of course, to make a machine, the sole function of which is to lubricate, dye, or otherwise treat threads or filaments, but it is usually desirable to eliminate such an extra operation and to apply the fluid to the threadas it passes through a machine such as a dry spinning, a rewinding or twisting machine, or the like.

What I 'claimjas new and desire to secure by Letters Patent of the United States is:

1. In a machine for fluid treating thread, a wire mesh screen, means for guiding thread into contact with a portion of said screen, and means for filling the interstices of the screen with a thread treating fluid.

2. In a machine for fluid treating thread, a wire mesh screen, means for guiding thread into contact with a portion of said screen, and means for filling the interstices 'of the "screen with a thread treating fluid, the wires of said screen being positioned at an angle to the path of the thread.

3. A fluid treating device for threads or the like, comprising a feed pipe, a wire guide, a wire mesh screen passing around said guide, a fluid feed pipe, said screen also passing around said feed pipe, means for passing fluid from said pipe to said screen to fill the meshes thereof, and means for guiding thread into contact with the screen near the wire guide to receive fluid therefrom.

4. A fluid treating device for threads or the like, comprising an endless wire mesh screen, two supports for the screen including a perforated pipe and a wire supporting rod parallel to the pipe and spaced apart, said endless wire mesh screen passing around the perforated pipe and rod and covering the perforation in the feeding pipe whereby said screen may receive fluid therefrom, a guiding means for directing a thread into contact with a portion of said screen to receive fluid therefrom, the individual wires in said screen being positioned at the contact point with the thread in non-parallel relation to the thread.

'5. A fluid treating device for threads or the i like, comprising an endless wire mesh screen, two supports for the screen including a perforated feed pipe and a wire supporting rod parallel thereto, said feed pipe being located above the supporting rod, said wire mesh screen covering said perforation in said feed pipe and being adapted to receive fluid therefrom, a guiding means for directing a thread into contact with a portion of said screen to receive fluid therefrom, the fluid passing from the perforated fluid pipe and being adapted to flow down through the interstices of said screen by gravity whereby the fluid removed by the thread may be automatically replaced.
